I don’t shop enough to know but are you saying that a replacement fork that fits your bike is unavailable? From anywhere?

I realize the 1.5-1.125 taper is the most common. It’s the only taper size I knew existed in fact. But there’s lots of funny stuff out there.

If you want to keep your frame, seems like it’s worth it to track down something that fits.

Every 1.125 straight fork in the world should work if you get a 1.25-1.125 bottom cup. Seems like a solid idea.

Custom might be harder than it sounds because even custom makers source readily available parts. If they can’t source a steerer tube, you might be out of luck.

How do you put a cup in a headtube that accepts bearings directly?

The Ritchey fork of the right dimensions was already discussed.

Have we reaches the dead horse stage?

The OP asked a straightforward question and got a straight answer long ago.

It might be time to holster the guns and move on.

Then why is the thread ongoing?

I misused the word “cup”.

Theres definitely drop in bearings available to size down on the steerer tube. Same difference but not a cup. See how being on pedantic misses the whole point?

To the OP. Get a fork that fits and make sure it’s one that you can replace in case this happens again. Getting stranded with abandoned standards sucks for a bike you actually ride.

(yes, one of my bikes has Uniglide, but I hardly ever ride it)
